(Cl. 206-56) This invention relates to a receptacle for fae (spraying aperture) in its wall m or in the cilitating the dispatch and storage of pastes, middle of the cover as, if necessary detachable making their removal more easy and thus superfrom the wall, and a bottom oz.

A piston I0 is provided part having the larger diameter being made of in the part I and a piston 20 in the part 2. The

The piston 20 is actuated by the part I. When 56 One receptacle part a has a discharge spout the two receptacle parts I and 2 are telescoped in the opposite direction to the arrows P1 and P2, the edge Id of the wall Ia bears against the piston 2c and shifts the same in the direction of the arrowPz. The tube 3 bears against the bottom it.

According to Fig. 4 a discharge nozzle 4 is provided in the bottom' lb of the receptacle part I. According to Fig. 6 the nozzle 4 is in the bottom 2b of the receptacle part 2. In the forms of construction shown in Figs. 4 to 6 at least the wall 2a of the receptacle part 2 of larger internal diameter is made of tearable material like cardboard, which is preferably impregnated. The wall 2a is made so long that it extends substantially over the whole wall Ia of the part I. The wall 20. is subdivided into transverse zones 28 on a portion of its length by weakened portions 211 similar to perforations. That portion of the length of the wall 2a which engages over the wall Ia has the above mentioned weakenings 2d. These may be real perforations or weakened portions of material, in which the material is not partly removed, but is weakened continually by stamping (incising). The transverse zones 2e are separated by one or more perforation-like weakened portions 2f extending in the direction of movement of the receptacle parts .I, 2. These weakened portions 2!, which, however, might also extend in a helical line, are arranged mutually displaced.

When the two receptacle parts filled with a paste are telescoped by exerting pressure on the bottoms lb, 217 (Fig. 5), the edge Id of the wall Ia pushes the piston 20 in the direction of the arrow P: into the receptacle part 2. The piston Ic also moves in the direction of the arrow P1 within the receptacle part I (Fig. 5).

In the-form of construction illustrated in Fig. 4 the paste in the receptacle part 2 is pressed by the movement of the piston 20 through the apertures 3a into the tube 3 and thence discharged from the receptacle part I. The contents of the part I are compressed by the movement of the piston I and escape through the nozzle 4.

In the form of construction illustrated in Fig. 6 the contents of the receptacle part 2 are forced through the apertures 3a in the tube 3 into the discharge nozzle 4 by the movement of the piston 2c. By the movement of the piston Ic the contents of the receptacle part I are compressed so that they flow through the tube 3 into the discharge nozzle 4.

When the container part I has been pressed into the part 2 a distance corresponding to the height of a transverse zone'2e, a strip corresponding to a transverse zone is torn off. The

displaced arrangement of the perforations 2f prevents the wall 2a from being accidentally tom too deeply in the direction of movement of the receptacle parts when tearing oiI a strip 5 corresponding to the height of a transverse zone is.

The perforated portion of the wall 2a forms a good guide for the part I. The wall 2a, however, does not hinder the telescoping ot the two receptacle parts I, 2, because its height can be reduced corresponding to the actual consumption by tearing off the zones 2e.

We claimzl. A receptacle for pastes, comprising in combination two telescopic parts, partitions separating said parts, and a riser tube extending through said partitions and establishing connection between said parts.

2. A receptacle for paste, comprising in combination two parts slidable one within the other,

each having a bottom and a cover, and a riser tube" fixed on the bottom of one of said parts extending tightly fitting through the bottom of the other of said parts and terminating in the cover of said first mentioned part.

3. A receptacle as specified in claim 1, in which the riser tube has an inlet aperture at its lowest portion adapted to allow the passage of the paste displaced by the telescoping of said parts.

4. A receptacle as specified in claim 1, in which the two parts have each a bottom and a cover, the cover of one part adapted to form abutment for the bottom of the other part when the parts are in extended position.

5. A receptacle as specified in claim 1, in which the wall of at least the part having the larger internal diameter is made of tearable material similar to cardboard and made so long that it extends substantially over the entire length of the wall of the other part, the wall of the part having the larger internal diameter being subdivided into transverse zones along a portion of its length by weakened portions of the material similar to perforations.

6. A receptacle as specified in claim 1, in which the wall of the part having the larger internal diameter is made of tearable transverse zones along a portion of its length by perforation-like weakened portions of the material and the transverse zones are subdivided in the direction of movement of the receptacle parts by at least one perforation-like weakened portion, the weakened portions of the individual transverse zones being mutually displaced.
